Abstract
D101 macroporous resin combined with high speed counter-current chromatography (D101 MR-HSCCC) was used to separate gallic acid (GA) from Cornus officinalis, and GA was added to starch-based products to improve food quality. The interaction and action mechanism of corn starch (CS) with GA were investigated for prediction and thereby controlling the structure and functions of starch-based foods. Results show that GA with 98.72% purity was successfully obtained using the D101 MR-HSCCC technique. HSCCC solvent system was composed of n-hexane-ethyl acetate-methanol-water (1:5:1:5, v/v/v/v). GA inhibited CS dissolution and improved CS swelling. Based on the particle size distribution, GA could enlarge the size of CS-GA complexes. FT-IR spectra exhibit that the interactions between CS and GA may comprise the intermolecular hydrogen bond and non-covalent bond. The results of XRD, LF-NMR and AFM show that the presence of GA could increase the relative crystallinity of CS, decrease the spin relaxation time (T2), and change the surface morphology of CS via the modification of hydrogen bonds distribution. Finally, SEM analysis indicates that GA could change the microstructure of CS-GA complexes. These findings facilitate the development of CS-based products and utilization of CS.

Abstract
Background:
Kuding tea, a Traditional Chinese drink, has a history of thousands of years
in China. Triterpenoid saponins in Kuding tea are regarded as one of the major functional ingredients.
Objective:
The aim of this paper was to establish separation progress for the isolation and purification
of five triterpenoid saponins (kudinoside A, C, D, F, G) from Kuding tea.
Methods:
Nine types of resins, including seven macroporous resins and two MCI-GEL resins, were
firstly used for purifying triterpenoid saponins by the adsorption and desorption tests. Further dynamic
adsorption/desorption experiments were carried out to obtain the optimal parameters for the five
targeted saponins. Then the purification of five triterpenoid saponins (kudinoside A, C, D, F, G) was
completed by semi-preparative high-performance liquid chromatography (semi-pHPLC).
Results:
As of optimized results, the HP20SS MCI-GEL was selected as the optimal one. The data
also showed that 65.24 mg of refined extract including 7.04 mg kudinoside A, 3.52 mg kudinoside C,
4.04 mg kudinoside D, 4.13 mg kudinoside F, and 34.45 mg kudinoside G, could be isolated and purified
from 645.90 mg of crude extract in which the content of five saponins was 81.51% and the average
recovery reached 69.76%. The final contents of five saponins increased 6.91-fold as compared
to the crude extract.
Conclusion:
The established separation progress was highly efficient, making it a potential approach
for the large-scale production in the laboratory and providing several markers of triterpenoid saponins
for quality control of Kuding tea or its processing products.

Traditional Tibetan medicinal plants: a highlighted resource for novel therapeutic compounds. Future Med Chem 2018; 10:2537-2555.

Abstract
Around 70-80% of drugs used in traditional Tibetan medicine (TTM) come from Qinghai Tibet Plateau, the majority of which are plants. The biological and medicinal culture diversity on Qinghai Tibet Plateau are amazing and constitute a less tapped resource for innovative drug research and development. Meanwhile, the problem of the exhausting Tibetan medicine resources is worrying. Here, the latest awareness, as well as the gaps of the traditional Tibetan medicinal plant issues in drug development and clinical usage of TTM compounds, was systematically reviewed and highlighted. The TTM resource studies should be enhanced within the context of deeper and more extensive investigations of molecular biology and genomics of TTM plants, phytometabolites and metabolomics and ethnopharmacology-based bioactivity, thus enabling the sustainable conservation and exploitation of Tibetan medicinal resource.

Abstract
Hyperoside, 3'-O-methylquercetin 3-O-β-D-galactopyranoside, astragalin and 3'-O-methylquercetin 3-O-β-D-glucopyranoside from an invasive weed Solanum rostratum Dunal were separated and purified successfully by high-speed counter-current chromatography (HSCCC) with a solvent system composed of n-hexane-ethyl acetate-methanol-water (1:7:1:7, v/v) and gradient elution mode preparative high-performance liquid chromatography (prep-HPLC) with low column temperature. In the sample pretreatment section, target compounds in aqueous extract of the weed were concentrated using solvent sublation. Two target fractions with purities of 93.75% and 93.68% were obtained from HSCCC. Their chemical structures were identified. The fraction 1 is a pure compound hyperoside and the fraction 2 is the mixture of astragalin, 3'-O-methylquercetin 3-O-β-D-galactopyranoside and 3'-O-methylquercetin 3-O-β-D-glucopyranoside by nuclear magnetic resonance and liquid chromatography-mass spectra. Then, the three flavonol glycosides in the fraction 2 were separated and purified successfully by prep-HPLC with low column temperature.
